PL2773 USB3.0/eSATAII to SATAII Bridge Controller. The PL2773 is a single-chip SuperSpeed USB3.0 or eSATAII to SATAII compliant bridge controller that is designed to perform seamless protocol transfer between the USB3.0/eSATA and SATAII interface. The PL2773 is implemented according to the USB Mass Storage Class driver. It supports USB3.0 SuperSpeed with 5Gb/s bandwidth and eSATA with 3Gb/s bandwidth. SuperSpeed USB 3.0(5Gb/s) delivers ten times the performance of Hi-Speed USB 2.0(480Mb/s) while offering backward compatibility with the billions of USB-enabled PCs and peripheral devices. It is fully backward compatible to all USB 2.0 and USB 1.1 hosts and operates under SuperSpeed, Hi-Speed, and Full-Speed USB connections. eSATA Mode has data bandwidth with 3Gbps and backward compatible with 1.5Gbps. The PL2773 also has an embedded high performance 8-bit microcontroller that can be used to support versatile system applications such as one button backup, power control, and other features for USB/eSATA port.

PL2775 USB3.0 to Dual SATA RAID Controller. The PL2775 is a low-power single-chip SuperSpeed USB 3.0 to Dual SATA II compliant bridge IC controller specially designed for external USB 3.0 dual-port RAID and non-RAID applications. It supports RAID 0 (striping) and RAID 1 (mirroring) as well as JBOD (Just a Bunch of Disks) and BIG (single logical disk) mode configurations. The PL2775 can perform seamless protocol transfer between the USB Host and dual SATA interface storage devices like Hard Disk Drives, Optical Disk Drives, and Solid-State Drives. SuperSpeed USB has data transfer bandwidth of up to 5Gbps offering 10X performance increase over Hi-Speed USB (480Mbps) while still retaining backward compatibility and interoperability with all USB 2.0 and USB 1.1 devices, hosts, and hubs. The PL2775 also integrates a high performance 8-bit microcontroller which can be used to support versatile system applications such as one button backup, power control, and other USB port features. The PL2775 chip is also implemented according to the USB Bulk-Only Mass Storage Class Specification v1.0.
